Re: Ford 850 1956. hydro trbl. lifting

If you only have 3ph, just install it in a convenient place by teeing into the pressure hose. If you have FEL, tee it in at the input to the FEL valve. If you are not using any hyd power, the gage will read low pressure. If any valve is activated, the pressure developed will be reflected on the hyd pressure gage. You will now have a way to set/adjust the relief valves .
